IMPROVEMENT IN WTEIifWHlEIELSl TO ALL `W HOM IT MAYv CONCERN: l

Be it known that I, JOHN C. TRULLINGER, of Oswego, in the county of Clackamas, and State of Oregon, have invented a new and useful Improvement in Water-Wheels `and do hereby-declare that the following is a full, clear, and exact description of the construction and operation' thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon.

' To enable others skilled in the art to makeand'use my invention, I will proceed to describe its construction and operation, and for that purposeI refer to accompanying drawings upon Sheets No. I and No. 2.

The drawings upon Sheet No. l represent the wheel andcases upon a horizontal shaft. The drawings upon Sheet No. 2 represent the wheel upon a vertical shaft, and the plan and sectional views of the buckets. Y

l Figure 1, upon Sheet No. 1, is a perspective view of the wheeland cases, with one part of the case removed' suciently to show the guide-plates, gates, and wheel combined.'

Figure 2, upon Sheet No. 1, is a perspective View of the wheel and buckets. Figure 3, upon Sheet No.1, is a longitudinal sectionof the wheel. y Figure 4, upon Sheet No. 1, is an elevation ofthe wheel and case. y Figure 5is a plan or transverse section. y p p Figure 1.

Figure l, upon Sheet No. 2,' is an 'elevated view'of the wheel and case together upon a vertical shaft.

Figure 2, upon Sheet No. 2,- isl a longitudinal section of the wheel and case. Figure 3, upon Sheet No 2, isa plan view of the rack. Figure 4, outlines of bucket and bridge. l Figures 5 and 6, upon Sheet No. 2, are sectional views of thebuckets. Figure 1. C, in iig. 'l, sheet 2, gates; F, ring; I, uppercase. l v Figure 2.

Figure 4. `L N represent outer edge of the bucket; L M N, the base of the bridge Q. Figures 5'and 6. A, diaphragm; B, buckets; Q, bridge. The outer edges of the buckets B 'B are covered from L to N, as shown by fig. 4, upon Sheet No. 2, and the bucket is also covered in all directions from the line L M N, the base of the bridge, to the line L N, the outer edge of the buckets. The wheel is to be used both as a perpendicular and horizontal wheel. The wheel upon a horizontal shaft vin the cases is set on theloor of the penstock, and the apertures cut in theiioor for the escape of the water from the cases. The water is'admited to the buckets of the wheel through the apertures oi' the stationary guides D D -by the gates C C, which are movedand adjusted by means cfa series of levers, G G', attached to the bases, F, of the movable ring F. By the direction given tothe water by the guides D D, it is imping'ed against the fore part of the buckets B -B at the greatest diameter of the wheel, and, by means of the peculiar cur've of the buckets in discharging, reacts upon the outeredge of the buckets and greatest diameter of the wheel, so that the smallest quantity of water-is used with as great a percentage of power as the largest quantity, or, with a full gate open, the water is discharged each way into the cases E E. v

IWhen the wheel is set upon a perpendicular shaft, the water is admitted. by means of the gaterrig in the same manner as when the wheel is on a horizontal shaft, and impinges upon the bucket and reacts in the same` manner, but discharges down through the lower case, and up over and down through the centre ofthe wheel. The wheel is suspended by means of the hoop and hub K, as shown by hg. 2, upon sheet 2, which is attached
